3. A modified/extended version of Pascal's wager. In other words, it is safer to accept Jesus as the Son of God and be wrong than it is to reject Him and be wrong.
Pascal's Wager doesn't really work in Christianity because it is a faith based religion, not a works based religion.
Read the post again. I wasn't applying Pascal's wager to the existence of God; I was applying it to the belief in Jesus as the Son of God. I realize this wasn't the way it was originally used, but it still applies.
And why would it only apply to works-based religions? Believing that God exists requires as much faith as believing that Jesus is His Son.
See Hosea 6:6 and other similar verses. The Abrahamic version of god is not interested in outward show, but sincere belief. A person whose reason for belief is Pascal's Wager does not strike me as being sincere. A god which is interested in the outward aspects such as works, can be propitiated by them regardless of the reason they are done.
